ORE-CONGENTIRATOR.Y

SPECIFICATION forming part of Letters Patent No. 756,305, dated April 5, 1904.

Application filed June 17, 1903.

To au whom t may concern,.-

Be it known that I, CALVIN G. WELLER, a citizen of the United States, residing at Idaho Springs, in the county of Olear Creek and State of Colorado, have invented certain new and useful Improvements in Ore-Concentrators, of which the following is a specification.

The chief intention of this invention is to devise a concentrator of novel construction for separating the verysfme or floating slimes from the water and feeding it onto a suitable table with as little wash-water as possible, so as to `save a good percentage of the precious metal that usually goes to waste in the ordinary operation of concentrating and stampmills. j

In thedrawings hereto attached and forming a part of the specification, Figure 1 is a perspective view of an ore separator or concentrator embodying the invention. Fig. 2 is a vertical central section thereof.

Corresponding and like parts are referred to in the following description and indicated in both views of the drawings by the same reference characters.

The device comprises a body portion 1 of rectangular formation and a sloping or taper= ing bottom portion 2, provided with avalve-' controlled outlet 3. An inlet 4 and an outlet 5 are provided at opposite sides of the body, near the upper end thereof, the outlet being at a lower level than the inlet. A partition 6 is arranged a short distance from the wall or side of the body'provided. with the inlet 4, and provides a space 7, through which the water laden with ore passes into the device. A series of plates 8 project into the space 7 from the partition 6 andV incline downward toward their free ends. A corresponding series of plates 9 project into the space 7 from the wall or side of the body having the inlet 4 and likewise incline downward toward their free ends. V'Ihe plates 8 and 9 alternate and overlap, so as to compel the inflowing water bearing the ore to make a tortuous path, thereby materially assisting in separating the ne particles of precious metal and causing same to precipitate or settle into the tapered bottom portion 2, to be drawn off through the valved outlet 3. A fine-meshed screen 10 is arranged Patented April 5, 1904.

near the upper end of the body l, just below the plane of the outlet 5, and serves to catch any oating metal, such as flower of gold, tending to pass off with the outiowing water through the outlet 5.

The surplus water passing off through the outlet 5 is conveyed toa convenient point of discharge. The settlings and precipitates in the lower portion of the tapering part 2 are drawn olf through the valved outlet 3 onto a suitable table (not shown) and are free from the excess or unnecessary amount of water whichimpedes the separating and concentrat ing process. The screen 10 may be of any line-meshed material, such as wire cloth or fabric, and in order to dislodge matter adhering thereto, so as to prevent clogging, a knocker-frame'may be applied thereto and consists of crossed strips 11. A pin 12 projects upward from the strips at their point of crossing and is adaptedto transmit the blow or jar to the screen when it becomes necessary to violently agitate the same to dislodge matter adhering thereto. i

vThe side 1a of the body having the inlet 4 is vertical; but the side 1b of the tapered end portion 2 is inclined inward, thereby deiecti ing the incoming current of-water and ore from a perpendicular course 4and facilitating the separation of the light and heavy particles of metal as they glide over the inclined portion lb, the deiection serving to cause the initial separation, as will be readily comprehended.

Having thus described the invention, what is claimed as new isl. The herein-described device for use in connection with concentrating ore, the same consisting of a hollow body provided with a tapered lower portion having a valvedoutlet and having an inlet and an outlet at opposite sides, the outlet being at a lower level than the inlet and having the upper portion of the inlet side vertical and the lower portion inwardly inclined, a partition arranged a' short distance from and parallel with the vertical portion of the said inlet. side,oppositelyin clined plates projected into the space formed between said partition and the vertical portion of the inlet side of the body and alterynately disposed and having their inner ends overlapped, and a iine-meshed screen arranged near the upper end of the body just below the plane of the outlet, and a lmocker-frame applied to said screen for receiving a light blow when it is required to jar the screen to disodge material therefrom, substantially as set Orth.

2. The herein-described device for use in connection with concentrating ore, the same consisting of a hollow body provided with a tapered lower portion having a valved outlet and having an inlet and an outlet at opposite sides, the outlet being at a lower level lthan the inlet, a partition arranged a short distance from the side of the body having the inlet, plates projected into the space formed be- CALVIN G. WELLER.
